The element of photography I enjoy the most is the ability to capture the same sights our eyes see, just a little differently. By playing with aperture and shutter speed we can bring out detail that the human eye doesn't see. By changing lenses we can achieve new perspectives.
I use prime lenses for all my photographs. Taking away the convenience of the zoom makes me think differently about how to capture the shot I want. Instead of the twist of a zoom, I have to get on my feet and go find the best frame. This invariably leads to more experimentation and often results in shots taken from angles I would not have otherwise considered.
